Pulling events from Google Calendar?

We list our daily opening/closing hours on a Google Calendar as Events. After some struggles with the Javascript API, we are almost able to extract the hours (events) for today and for tomorrow to embed elsewhere on the site -- but at 7pm local time (EST in the US) it kicks over to the next days' listings.

That seems to be 0:00 GMT, when it switches, yet the calendar itself displays as it should for our time zone. For some reason I'm too dumb to find, the script is pulling the events in a way that almost does does but doesn't quite correspond with the calendar.

Any ideas on how to solve this? (I'm open to even inelegant workarounds.)

We are pulling the events. What we don't understand is how to fix the 5-hour offset.

If user sees the event we pull right now (Sunday at half-past six in the morning) it's fine, it shows our hours for Sunday. Same deal at noon. And at 4pm, and so on--up until 7pm, when it will instead show the hours for Monday.
